It is also found that the active surface may be changed and can be recovered under the reaction conditions, and that the high activity may be obtained often accompanied by high selectivity, high resistance to carbon deposition and good product distribution. 重整反应气氛下催化剂的活性表面是可变和可恢复的,而高活性、高选择性及高抗积碳能力与合理的产品分布是一致的。

For the effects of oil price rising and greenhouse gas reducing, the recovery of carbon dioxide in power plants flue gas had been developed adequately. The recovered carbon dioxide can be used in flooding enhance oil recovery directly. 在国际油价上涨、温室气体减排等因素影响下,电厂烟道气回收技术得到了充分发展,回收的高纯度二氧化碳可直接用于油田强化采油。
The natural secondary forests recovered in the region over many years play an increasingly important role in the forest biodiversity conservations and ecosystem function services. They also are the important value-added points of environmental restoration and carbon emissions. 多年来该区域恢复起来的天然次生林在我国保护森林生物多样性,发挥生态系统功能等方面起着越来越重要的作用,是我国环境恢复和碳排放的重要增值点。
